Trigger assembly

ABSTRACT

A trigger assembly includes a body having a pivot, and a hook is mounted to the pivot. The body has a chamber, and a path communicates with the chamber. A first positioning unit is located in the path, and a safety member is located in the chamber which has two slots and the. The first positioning unit contacts the slots. An activation member is located on the top of the safety member and has a guide groove and a positioning hole. A guide rod on the safety member is located in the guide groove. A second positioning unit is located in the body and contacts the positioning hole. A pivotal member is pivotably connected to the body and has an end contacting a push portion of the activation member. A spring is mounted to the protrusion and contacts the inside of the body. The trigger assembly includes two safety protections.

FIELD OF THE INVENTION

The present invention relates to a trigger assembly, and, moreparticularly, to a trigger assembly with two safety units.

BACKGROUND OF THE INVENTION

A conventional trigger assembly is shown in FIG. 9 and generallyincludes a body “A” in which an activation plate A1 is slidably insertedtherein which has two positioning recesses A11 in the top thereof, andeach positioning recess A11 has a positioning member A2 receivedtherein. A safety plate A3 is pivotably connected in the body “A”, and apivotable member A4 is pivotably connected in the body “A” and locatedclose to the safety plate A3. The free end of the pivotable member A4 isconnected to the body “A” by a spring A5, and a trigger A6 is connectedto the lower side of the body “A”. The trigger assembly is used to shootarrows.

However, the conventional trigger assembly does not have two safetyunits, so that when the arrow is in position, the safety plate A3 andthe activation plate A1 are moved backward. The pivotably member A4 islowered because of the force from the spring A5. If the userunintentionally pulls the trigger A6, the arrow may touch the rear endof the pivotable member A4 and generates a huge noise which may scarethe user.

The present invention intends to provide a trigger assembly whichimproves the shortcomings of the conventional trigger assembly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 1 to 8, the trigger assembly or of the presentinvention comprises a body 10 having a presser 11 and a trigger pin 12located at the lover side of the body 10. A trigger 13 is pivotablyconnected to the body 10 by the trigger pin 12. and has a contactportion 131 formed on the top of one side thereof. A phi pin 14 contactsthe contact portion 131, and a trigger spring 15 is mounted to the pin14. A free end of the trigger spring 1 15 contacts the body 10 which hasa pivot 16 located close to the trigger pin 12. A hook 17 is mounted tothe pivot 16 and has a resilient member 171 connected thereto. A cap 18is securely connected to one side of the body 10, so that the trigger 13and the hook 17 do not drop from the body 10.

The body 10 has a chamber 101, and a path 102 communicates with thechamber 101. A first positioning unit 20 is located in the path 102, anda safety member 30 is located in the chamber 101. The safety member 30has two slots 31 defined in the underside thereof, and the firstpositioning unit 20 contacts the slots 31. A guide rod 32 protrudes fromthe top of the safety member 30. An activation member 40 is located onthe top of the safety member 30 and has a guide groove 41 and apositioning hole 42. The guide rod 32 is located in the guide groove 41.The A second positioning, unit 50 has a bolt 60 connected to a topthereof. A The second positioning unit 50 is located in the body 10 andcontacts the positioning hole 42. A pivotal member 70 is pivotablyconnected to the body 10 and located close to the hook 17. The pivotalmember 70 has an end normally contacting forming a push portion 71contacting on the top of the activation member 40. A protrusion 72extends from the top of the pivotal member 70, and a spring 73 ismounted to the protrusion 72. A free end of the spring 73 contacts theinside of the body 10.

In this embodiment, the resilient member 171 is a spring, and the firstand second positioning units 20, 50 are a bead and a springrespectively.

The body 10 has a gauge 80 on the top thereof, and an adjustment button90 is located on one side of the body 10. The pivotal member 70 has alever 74 connected thereto.

When not in operational status, the second positioning unit 50 ispositioned to the positioning hole 42, and the first positioning unit 20is positioned to the slot 31 of the safety member 30. When the safetymember 30 is moved back and locked as shown by the arrowhead in FIG. 5,the how bow string pushes the activation member 40 to remove the secondpositioning, unit 50 from the positioning hole 42, and the activationmember 40 is moved backward. The safety member 30 performs as a “switch”to lock the trigger assembly as shown in FIG. 6. When the arrow (notshown) is installed, the push portion 71 of the pivotal member 70 ispushed by the arrow, and the activation member 40 is not activated, sothat the “switch” is opened as shown in FIG. 7. When the trigger 13 ispulled, the pivotal member 70 moves forward to shoot the arrow, and theactivation member 40 contacts the pivotal member 70 as shown in FIG. 8.Therefore, the shooting processes are completed. The present inventioninvolves fewer parts and has two safety protections to avoid the hugenoise due to that the user unintentionally touches touching the trigger.
